た。(Prior Art and Problems) Conventionally, in a gasification premix type oil combustor, the combustion state is detected mainly by detecting changes in flame current value due to flame rods. However, in the case where the combustion capacity is switched, when the combustion capacity changes, the flame current value also changes, and it is necessary to change the abnormal state level of the flame current value for each capacity. In addition, the flame current value changes during ignition and steady combustion, and there is a level difference in flame current value even during normal combustion. Therefore, in order to detect abnormal combustion, it is necessary to Detailed level settings were required.
本考案は大まかなレベル設定でも異常燃焼を確
実に検出し、複雑な制御装置を必要としない経済
性の高い異常燃焼検出装置の提供を目的とするも
のである。 The present invention aims to provide a highly economical abnormal combustion detection device that can reliably detect abnormal combustion even with rough level settings and does not require a complicated control device.

This is a heat collector facing above the burner 3 from the top surface. Reference numeral 5 denotes a flame rod, which is arranged between the burner 3 and the heat collector 4.

のレベル設定はリフト側だけで良い。 Next, the effect will be explained. During normal combustion, flame current is detected by flame rod 5. When abnormal combustion occurs due to lack of air or the like, a significant amount of soot adheres to the flame rod 5 and grows upward as it is carried away by the combustion gas. When the soot column comes into contact with the heat collector 4, current flows from the flame rod 5 to the heat collector 4 and the burner 3, and no flame current flows. At this time, the current value of the current flowing through the heat collector 4 becomes much smaller than the flame current value during normal combustion, and is at the same level as flame non-detection, so abnormal combustion can occur even if the current value is not set in detail. can be identified. When there is excess air, it detects changes in flame current due to flame lift and operates safely. Therefore, the level setting of the flame current value only needs to be done on the lift side.
